holder, by means of which the buck cover is held taut; and

Figure 12 is a view of thekey by means of which the buck cover holder ofFigure 11 may be manipulated as during installing and replacing the buckcover.

Referring now to Figure l, the buck generally designated' is supportedby base casting 11 on its support plate 12 by cap screws 13. Plate 12 isin turn supported by angle members 14 attached to a mounting plate 15which is secured to the frame of a pressing machine in any conventionalmanner.

The pressing machine, with which this buck is used,

forms no part of this invention per se and consequently An exemplaryform of pressing machine with which this buckmay be used is disclosed inour co-pending application, Ser. No. 307,456, as aforesaid. The basecasting 11 of the spatulate buck 10 has a flange at 16 and is hollowinside except for an angularly disposed Web 17 which connects the sideWalls. It is to this base casting 11 that the plates 18 of the spatulateform are attached bypins 19' passed through apertured washers 19A.Referring to Figure6, it is seen that these plates 18 are generally flatbut are curved toward each other at the front edges 18A. The rear edges18B of these plates are welded into longitudinal. grooves at 18C whichare milled in a heavy Walled steel tube 20. The attachment of the edges18B to the steel'tube 20 may be by welding, copper brazing or othersuitable fastening means, the only essential being that the fastening bemechanically strong and capable of ready transmission of heat from thetube 20 to the plates 18.

The plates 18 are attached to the base casting by means of pins 19, andare separated by washers 19A. Plates 18 serve as supports for the tubeor pipe 20. The pipe 20 is plugged at its upper end by plug 21 1 and hasits lower end adjacent the lower edge of the plates 18 bent at 22 so asto extend down through the hollow base casting 11, through the hole backof web 17 therein. The pipe 20 is again bent at 23 so as to extend downbetween the flanges 14 as at 24 of Figure 1 so as to allow steam andcondensate water connections to be made thereto.

Referring to Figure 9, it will be noted that pipe 20 extends down to aY-connection at 25. To one branch of the Y-connection is screwed thenipple '26 which has attached to it a smaller diameter tube 28,preferably of copper, which extends all the way up the pipe 20 andterminates adjacent the plug 21 at the upper end of the pipe 20. To thenipple 26, there is attached a coupling 29, which is in turn attached toa steam connection pipe, not shown. To the other branch of theY-conuection 25 there is attached a nipple which is connected to asuitable condensate water return, not shown. The introduction of thesteam at the top of the pipe 20 adjacent the plug 21 insures that a fullsteam supply is made to the entire interior surface of the pipe 20fandthe condensate is returned quickly and efficiently out of theipipe.

of the plates 18 are attached together by a top casting 32 which is heldin place by screws 33. The construction of one type of top casting isdescribed in our copending application, Ser. No. 145,258, now Patent No.2,687,241. The top casting may be of any desired type as to facilitatethe sleeving of a tubular form onto the spatulate buck, and forms nopart of this application per se.

While this invention has been described with reference to a verticallypositioned buck for use With tubular garment sections, it is to beunderstood that it may likewise be used with reference to a horizontallypositioned buck for tubular garment sections or to horizontally orvertically positioned bucks for use with other, garment sections.

Referring to Figure 8, it Will be noted that by milling the groove 18Cto approximately the thickness of the plate 18 a smooth outer surface isproduced at the junction of the plates 18 and the tube 20, plates 18being easily ground off and polished, if desired. Upon the smoothexterior surface thus formed by the two plates 18-18 and the tube 20,there is mounted a suitable buck padding of one or more layers 31 and34. The layer 31 is preferably made of cloth knitted from rust resistantWire, such as Monel metal, or the like, the pad being composed of aplurality of plies of such fabric. Upon such resistant woven metallicpad 31 is preferably laid a pad 34 comprised of one or more layers offlannel and over this there is tightly stretched the exterior buck cover35. Experience has shown that for the average surface encountered inpresses of this type, that the buck cover 35 should best be made withvery tough fabric, such as nylon fabric.

The attachment of the nylon cover 35 is accomplished in the followingway: The nylon cover has its opposite edges sewed so as to form headings38 and 39 in which there are placed thin, flat, comparatively narrowsteel rods 40 and 41. At the upper and lower ends of the space betweenthe steel side plates 18 there are provided brackets 42 which have holes43 longitudinally therethrough which serve as sliding supports for rods44. At the rear ends of the rods 44, there are washers 45 held in placeby'the cotter pins 46. To the front ends of each of the rods 44, thereis attached a T-shaped head 48 having a hole 49 therein. The spring 50is pressed between the bracket 42 and the washer 45 and tends to drawthe rod 44 back in the direction of the arrow 51, as shown best inFigure 10. The T-shaped heads 48 have a thickness such that when theyare turned so that the head lies parallel with the plate 18 theshoulders 52 and 53 will be disengaged from the ends of rods 40 and 41.In order to place the buck cover on the buck padding, the fabric 35 ispulled as tautly as possible by, hand over the buck padding and the tworods 40 and 41'are then tucked back It was found by lengthy experimentsthat thcheating of I the pipe 20 with high pressure steam providesadequate heat for the elimination of Water from the buck pads even athigh rates of ironing production and with damp shirts, it was found alsothat by having theplates 18 welded or otherwise firmly connected tothe-pipe 20, that Th'eiupperuendsa long shank 54, a turned over end-55and a handle 56.

The shank 54 is inserted into the space between the front edges of thebuck padding and the plates 18 until the hook end 55 can be'engaged inthe hole 49 of the T-shaped head 48. The head is then drawn forwarduntil it clears I the rods 40 and 41 and is then turned so that theshoul the heat is conducted adequately throughout the area of the plates18 and hence given off on the surface ofthe' ders 52 and 53 engagegrooves in the ends of rods 40 and 41, respectively. Then the T-shapedhead 48 is permitted to be retracted under the influence of spring 50and this throws a tensioning pressure on the rods 40 and 41, whichaccordingly draw the nylon fabric 35 closely and tautly over the buckpadding.

It will be noted, from Figure 10, that over the front edges18A of eachof the buck plates, there is a small member generally designated 58which has a flange 59 also toembrace the front curved-in tip 18A of'theplate 18. The member 58 is a light stainless metal and is curved to fitthe front bend 18A of the plate 18. Howing thereof.

arm 69 and alower crank, arm 70. Bellcrank lever 68 is pivoted at thepivot 71 for arcuate movement. This bell-icrank lever. arm 69. whichextends; upwardly 1 between the plates. 18 andthespatulatebuckstructure,has spaced members and carries .pivot 66.. upon which the'slotte'd lug64 is hung. The lever arm 69 extends down between the plates 1818 and isbent so as to operate within the front opening in the base casing 11 andthen extends downwardly to the pivot 71 whence it extends V forwardly atthe portion 70. This forward portion 70 said co-pending divisionalapplication. Since such adjustment rod and the wing structure form nopart of this invention per se, they will not be described in greater'detail. The pivotal mounting of the bell-crank lever arm 68 upon pivot'71 and the provision of pivot 75A allows attachment to pivot 75 of alink not shown which may be operated to propel the buck-wing outwardly(leftwardly with reference to Figure 3). The provision of operatoractuable rod 76 likewise allows this to be done selectively at theoperators discretion.

It will be noted from Figure 1 that the upper end of the buck isnarrower than the lower end and that the upper end is cut square whereasthe lower end of the buck, corresponding in the illustration of theshoulder seam of a shirt sleeve is at an angle. Thus, referring toFigure 1, the buck, generally designated 10, has a smaller front to backdimension at its upper end than at its lower end and the padding is atsubstantially right angles to the longitudinal axis of the buck at theupper end A .but is shaped at the angle along the lower end 10B. It willbe understood, however, that the shape of the buck may be varied toaccommodate the pressing of difierent shapes of garment elements. A.
